SEPARATOR FOR STEAM-BOILERS.

SPECIFICATION forming part of Letters Patent N0. 725,698, dated April 21, 1903.

' Applicationiea Apru 21,1902.,

TO all whom, it may concern:

Beit known that I, ROBERT HENRY GOAOH-` ER, a subject of the King of the United King- Woodsetts, near Worksop, in the county of York, England,have invented new and useful Improvements in Separators for Steam-Boilers, of which the following is a specification.

This invention relates to improvements in steam-boilers, the object being to *provide means for preventing priming by admit? ting only dry steam to steam dome or delivery pipe.

In carrying my invention into eect I cause the steam to reach the steam dome or delivery pipe by passing between a plate and the shell of the boiler.

In the accompanying drawings, Figures l, 2, and 3 show in longitudinal section several modes of attaching the plates in position, and Fig. 4 is a cross-section of Fig. l, and Fig. 5 a longitudinal section of a modication.

Referring to Fig. 1, a is a boiler-shell; b, the steam-dome; c,'the opening in the boiler, of less diameter than the dome, so as to provide an instanding ledge CZ. Through the ledge d are passed downward the screwthreaded bolts e, which pass through plain holes in the separatorplate f, having upwardly and outwardly turned ends g. The plate f extends across the boiler a few inches below the dome b andv is kept in place Onthe bolts e by the nuts h.

Fig. 2 shows the separator-plateattached to the blockj of the delivery-pipe by bolts 7o, screwing into the block j, as at Z.

In Fig. 3 the separator-plate mis shown as suspended by a bolt n, the head o of which is carried by the'cross-b'ar 29, one end of which is plain, as at q, and the other screw-threaded,

serai rfionoasv.' (No maar.)

as at r. The screw-threaded end fr of the the block. Lock-nuts u keep the outer ends of the pipe s and that of the plain end q in their respective recesses on opposite sides of the block j.

The separator-platesmay be ilat, with the Vends'turned up, they may be curved from end to end upward'or downward,with or without turned-up ends, and they may be perforated or not.

In substitution for the separator-plates I sometimes use an open under tube w, as shown in Fig. 5. In this case the tube has a central opening communicating with the dome or steam-delivery pipe.

In cases where the plate is wider .than the manhole ofthe boiler it may be in two pieces, which can be bolted up when inside the boiler.

What I claim as my invention, and desire to secure by Letters Patent, is-

For preventing the immediate access of steam to the steam-dome, an instanding ledge surrounding the mouth of the steam-dome: bolts Vdepending from the said instanding ledge and a plate of greater length than breadth suspended by the said depending bolts and having its shorter sides outwardly upturned, substantiall'yas hereinbefore described. l

rvI ngtestimony,whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ROBERT HENRY GOACHER.
